The Amazfit Helio Strap is a screenless band, which makes its broadcast the main way to see its heart rate anywhere else — on gym equipment, a bike computer, or an app of your choosing. Amazfit calls the feature heart rate push. Here is how to turn it on and what to expect from it.
How do I turn it on?
Open the Zepp app, choose your Helio Strap under Device, and open Health Monitoring — the heart rate push setting lives there. Turn it on, and the strap broadcasts on the standard Bluetooth heart-rate profile. Amazfit’s support page describes connecting it to third-party Bluetooth devices such as watches, cycling computers, and treadmills; in practice, anything built to read a chest strap qualifies.
Does it broadcast all day, or only in workouts?
Amazfit’s documentation doesn’t address this, and it is the question that decides what the feature is for. In our testing, the answer is all day: with heart rate push on, the Helio broadcasts continuously through ordinary wear — desk hours, walks, sleep — at roughly one reading per second, not just during logged sessions. That makes it one of the few trackers whose broadcast can describe a whole day rather than a workout.
How many things can read it at once?
In our testing, more than one — the Helio accepts multiple simultaneous connections. A bike computer and a phone app can both read the same broadcast without evicting each other. That sounds like a detail until you own a device that allows only one reader; then it is the whole difference.
What about battery?
The Helio is rated for around ten days per charge, which leaves real headroom for running the broadcast continuously. Amazfit doesn’t publish a broadcast-specific battery figure; expect some cost, and a strap that still comfortably outlasts the week.
Should I turn heart rate push on?
If you own a Helio and anything with a heart-rate readout, turn on heart rate push — it is the strap’s live signal, free to any software you choose. The broadcast is a standard, and brainful — the b-score app for Whoop straps — reads that standard: it listens to the heart-rate profile and puts a b-score (0–100) on each calendar event, on the phone — what each hour was actually worth. It was built and tuned on Whoop, but in our own testing the Helio Strap pairs and scores end to end today. Official support — including tuning for the Helio’s optical stack — hasn’t shipped yet, so early users are exactly that: early. If you own one, the door is open.
